This is a picture of an older manual focus Canon FD 28mm F/2.0 lens. The lens is in overall very nice shape - except for what has been developing inside of it.

What's your verdict? Garbage or worthwhile having it professionally cleaned?

Thanks!

I had a nice Sigma telephoto that developed fungus in the rear lens. I was told that it really couldn't be fixed, or wasn't worth fixing.

Most likely not worth the cost nor the risk. These can be bought on eBay for $100. I hate throwing away old glass but sometimes the value just isn't there...

Thanks! Do you want to buy the lens and switch to Canon?

Buy your lens a visit to a tanning salon. UV kills fungus.

Take the lenses out and have a great extension tube.

The lens is of minimal value. I would think it would be a good sacrificial lamb to your curiosity, disassemble it and try cleaning it yourself. Then see if you can put it back together properly. That's how I started repairing my own old lenses. Its fun, and rewarding when you get it back in shootable shape.

MT - Is there any concern with mold spores contaminating the camera or other lenses?

Shameless self-promotion:

I guess I'll try radiation first and wait with the surgery.

Thanks!

Sunshine will kill the mold but the dead mold will still be inside the lens. I would think you would have to open it up to clean it regardless. I like MT Shooter's solution. What have you got to lose? You might learn a few things that could save you a bunch of money on a more expensive lens someday.
